Conduction system of the heart. This 3d medical animation depicts the anatomy of the heart. Shape and size of the heart.

Right left superior and inferior. The heart is a hollow organ with four flexible and resilient inner chambers. Here we will review its essential components and how and why blood passes through them.

This amazing muscle produces electrical impulses that cause the heart to contract. Singly one is called an atrium from the latin word meaning entrance the lower chambers are called the ventricles from the latin word for belly the heart is also divided into two sidesleft and right. Layers of the heart wall.

The heart has three layers of tissue each of which serve a slightly different purpose. The heart pumps blood through the network of arteries and veins called the cardiovascular system. The heart has five surfaces.

The chambers of the heart are shown including the right atrium left atrium right ventricle and left ventricle. Heart anatomy inner chambers. The right atrium receives blood from the veins and pumps it to the right ventricle.

The heart is able to both set its own rhythm and to conduct the signals necessary to maintain and coordinate this rhythm throughout its structures. The right margin is the small section of the right atrium that extends between the superior and inferior vena cava. It is divided by a partition or septum into two halves and the halves are in turn divided into four chambers.

It also has several margins.
